Definitions

  • Some problems associated with fixed wall systems are the inability to displace and/or move the fixed wall systems once they are mounted. Fixed wall systems are also disadvantageous because their installation is quite lengthy. Some of the problems associated with moveable wall systems are that, very often, their components are over-engineered (e.g., too heavy), they require different and specialized tooling for assembly, and they generally comprise various different components which are not readily interchangeable. Some of the problems associated with non-progressive wall systems are the inability to independently change, move, and/or alter a particular component of the non-progressive wall system without affecting the other components operatively connected to the particular component.
